Prince asked fans to wear gray to the show in tribute to Freddie Gray, who was critically injured while in police custody. In addition to “Baltimore,” a song he dedicated to the town’s residents and fallen Gray, Prince journeyed through a medley of his hits including “Let’s go Crazy.” Marilyn Mosby, lead prosecutor in the Freddie gray case, also appeared onstage with the purple one in a moment that we’re sure sent the crowd into applause.

The Carters were also spotted grabbing a bite to eat earlier in the day.
